According to the corresponding angle test, what condition must be met for two lines to be parallel?

• A pair of alternate angles must be congruent

• A pair of corresponding angles must be congruent

• The lines must be perpendicular

• The lines must be skew

In the given figure, which line acts as the transversal?

• Line O

• Line N

• Line M

• Line L

What is the relationship between angles A and B in the figure?

• They are complementary

• They are supplementary

• They are adjacent

• They are congruent

What is the sum of angles A and C in the proof?

• 360 degrees
